Abstract
The invention discloses a preparation method of a strong cube texture Ni-5at%W alloy substrate initial billet and belongs to the technical field of synthesis of a texture metal substrate for a high temperature coating superconductor. In nonvacuum induction melting, appropriate aluminum powder and silicon-calcium powder are used and can be bonded with oxygen in a nickel-tungsten alloy liquid so that an oxide insoluble in the nickel-tungsten alloy liquid is formed and is discharged by buoyancy. In initial billet preparation, a forging process is avoided, the quadrate nickel-tungsten alloy billet is hot-rolled so that under control of hot-rolling deflection and a finishing temperature, the nickel-tungsten alloy initial billet with uniform crystal grain sizes is obtained. The preparation method can prepare the Ni-5at%W alloy substrate initial billet with high performances.
